DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The flood prevention pump of the present invention is a type of liquid variable volume machine and a part of the energy-saving and environmental protection industry. It is mainly used to cope with drainage tasks in flood disasters and rainstorms, to ensure the safety of urban infrastructure and people's lives, and is an important equipment for preventing flood disasters.

[0021] The automatic assembly equipment of the present invention belongs to the intelligent manufacturing equipment industry and is a kind of processing equipment, which is used to assemble the various parts that make up the pump body into a pump body.

[0022] Refer to the instruction manual Figure 1-Figure 4A subway flood prevention pump according to an embodiment of the present invention comprises a pump body 2, a pump seat 1 and a driving source 3. The pump seat 1 is fixedly arranged at the bottom of the pump body 2, wherein the bottom end of the pump seat 1 is set to a V-shaped structure, which can effectively reduce the resistance encountered by the flood prevention pump when it is put into water. The driving source 3 is fixedly installed at one end of the pump body 2 by a locking bolt. The pump body 2 comprises a pump casing 21. A driving shaft 22 is rotatably installed at one end of the pump casing 21 close to the driving source 3 through a bearing. The driving shaft 22 is composed of a cylindrical section and a fixed The pump housing 21 is composed of cross-square segments at both ends of the cylindrical end. A fixing frame 23 is fixed on the inner side of the pump housing 21. The fixing frame 23 is composed of a support plate and a collar fixed on the top of the support plate. A variable-capacity arc plate 24 is sleeved on the outer side of the fixing frame 23. The end of the pump housing 21 away from the driving source 3 is provided with a driving disk sleeved on the outer side of the corresponding end of the driving shaft 22. The end of the pump housing 21 away from the driving source 3 is fixedly installed with an end cover 28 by a locking bolt. The outer side of the pump housing 21 is also connected with an L-shaped suction pipe 4 and a discharge pipe 5 (see the installation position for details). Figure 1 ), when used specifically, a water delivery pipe can be connected to the water outlet end of the drain pipe 5 to guide the suctioned water to be discharged. At the same time, a filter assembly can be installed at the water inlet end of the suction pipe 4 to prevent debris in the water from being sucked in and causing blockage. In addition, flanges are fixed at both ends of the outer side of the pump housing 21 to facilitate the subsequent joint use of multiple flood control pumps; Further, the driving disc includes a disc 25 and a sleeve shaft 26 fixed at the center position of one side of the disc 25, a cross groove 1 adapted to the cross block segment at the corresponding end of the driving shaft 22 is opened at the axial centerline position of the sleeve shaft 26, and the cross groove 1 penetrates the disc 25, the sleeve shaft 26 is movably inserted in the inside of the collar, and at the same time, the cross block segment on the driving shaft 22 close to the sleeve shaft 26 is movably inserted in the inside of the cross groove 1, an eccentric disc 27 sleeved on the outside of the sleeve shaft 26 is fixedly provided on one side of the disc 25, one end of the collar is movably inserted in the inside of the annular cavity formed between the eccentric disc 27 and the sleeve shaft 26, and the variable capacitance arc plate 24 is movably sleeved on the outside of the eccentric disc 27; The driving source 3 includes a waterproof cover 31 fixedly installed on the outside of the pump housing 21 by locking bolts, and a motor 32 is fixedly installed inside the waterproof cover 31. The end of the output shaft of the motor 32 is fixedly connected to a sleeve shaft 33 for controlling the rotation of the driving shaft 22. One end of the sleeve shaft 33 is provided with a cross groove 2 that is compatible with the cross square segment at the corresponding end of the driving shaft 22.

[0023] It should be noted that after the variable capacitance arc plate 24 and the drive disk are encapsulated in the pump housing 21 by the end cover 28, the variable capacitance arc plate 24 always maintains the state of being sleeved on the outer side of the eccentric disk 27. At the same time, the support plate on the fixing frame 23 is just inside the straight seam formed by the two ends of the variable capacitance arc plate 24. After one end of the drive shaft 22 is inserted into the cross slot 1, the end of the cross slot 1 close to the end cover 28 is in an unfilled state. The depth of the unfilled part of the cross slot 1 is equal to the length of the cross block section on the drive shaft 22 that is plugged into the sleeve shaft 23. In the process of pumping water by using the flood control pump, the drive shaft 22 is rotated at a high speed by starting the motor 32, and the drive disk is driven to rotate synchronously by the high-speed rotating drive shaft 22. Due to the arrangement with the eccentric disk 27, the eccentric disk 27 rotates synchronously with the disc 25, so that the variable capacitance arc plate 24 not only moves in the vertical direction under the restriction of the support plate, but also swings in the left and right directions. The specific cycle process of the variable capacitance arc plate 24 is as follows: the initial state (i.e. the straight seams formed at both ends of the variable capacitance arc plate 24 are in the state of Figure 2 The lowermost position of the support plate as shown in the figure) → gradually moves upward and swings to the right at the same time. The outer side of the swing direction always moves in contact with the inside of the pump casing 21 after passing the water outlet end of the suction pipe 4, and squeezes the water entering the pump casing 21 to be discharged from the drain pipe. While discharging the water in the pump casing 21, the volume change inside the pump casing 21 is used to suck the external water into the pump casing 21 again → move upward to the highest point → gradually move upward and swing to the right at the same time → initial state; Furthermore, in actual application, if the drainage volume needs to be increased, the end cover 28 can be removed, and the end of another pump body 2 close to the motor 32 can be directly blocked with the end of the previous pump body 2 on which the end cover 28 is installed, and the two flanges at the opposite ends of the two adjacent pump bodies 2 can be connected and fixed by locking bolts, and so on, multiple flood control pumps can be used together (see Figure 4 As shown), it is only necessary to seal the pump body at the end with an end cover 28, and a plurality of flood control pumps used in combination can be driven by only one motor 32.

[0024] Example 1: Refer to the attached specification Figure 5-Figure 6 and Figure 8 An automatic assembly device for a subway flood control pump according to an embodiment of the present invention is used to assemble the pump body 2 of the above-mentioned iron flood control pump. The automatic assembly device includes a base 6, a bracket 9 is fixedly provided at one end of the top of the base 6, a support plate 10 is provided at the top of the bracket 9, and a transfer feeding mechanism 8 for rotating and alternately feeding the variable capacitance arc plate 24, the driving disk and the end cover 28 is provided at the top of the base 6 at one end of the support plate 10; The indexing feeding mechanism 8 includes a motor 2 fixedly mounted on the top of the base 6, the output shaft end of the motor 1 is fixedly connected to a vertical shaft, and a circular plate 82 and a rotating disk 81 are fixedly sleeved on the outer side of the vertical shaft from top to bottom in sequence, wherein the outer side of the rotating disk 81 is provided with a Figure 5 The notch shown in the figure has a central angle of 90° corresponding to the opening of the notch. Three straight plates 84 are fixedly arranged on the outer side of the circular plate 82 and are distributed in an annular direction around the vertical axis. The specific distribution of the straight plates 84 is shown in Figure 5 As shown, the ends of the three straight plates 84 away from the circular plate 82 are respectively installed with a variable capacitance arc plate feeding assembly 85, a drive disc feeding assembly 86 and an end cover feeding assembly 87, and the turntable 81 and the V-shaped block 78 are arranged in the same plane in a horizontal direction; The transfer loading mechanism 8 also includes three feeding components 83 fixed on the top of the base 6 and distributed circumferentially around the vertical axis.

[0025] It should be noted that in the process of assembling the variable capacity arc plate 24, the drive disk and the end cover 28 to the inside of the pump casing 21 on the top of the support plate 10 in sequence, the vertical axis is driven to rotate by motor 2, thereby driving the circular plate 82 and the turntable 81 to rotate synchronously, and the rotating turntable 81 is used to drive the three feeding components 83 in sequence to push the variable capacity arc plate 24, the drive disk and the end cover 28 they carry to the material picking station, and the rotating circular plate 82 will drive the variable capacity arc plate feeding component 85, the drive disk feeding component 86 and the end cover feeding component 87 to clamp the variable capacity arc plate 24, the drive disk and the end cover 28 on the corresponding material picking station when entering the material picking station, and when moving to the position of the pump casing 21, the variable capacity arc plate 24, the drive disk and the end cover 28 are accurately installed in sequence inside the pump casing 21.

[0026] Specifically, Figure 5-Figure 6 and Figure 10-11As shown, the variable capacity arc plate material assembly 85 includes a cylinder 1 851 fixedly installed on the top of the straight plate 84, the telescopic end of the cylinder 1 851 passes through one end of the straight plate 84 and is fixedly connected to a limiting plate 852, a limiting ring 853 is sleeved on the outer side of the limiting plate 852, and three cylinders 2 856 evenly distributed in an annular shape are fixedly installed on the outer side of the limiting ring 853, and the telescopic end of each cylinder 2 856 is fixedly connected to a top tightening plate 857, wherein a non-slip soft rubber pad is fixedly provided on the top tightening side of each top tightening plate 857, which can effectively prevent the clamped variable capacity arc plate 24 from falling off, and at the same time, An image sensor is installed at the bottom of the corresponding straight plate 84 to detect whether the straight seam on the clamped variable capacitance arc plate 24 is aligned with the support plate on the fixing frame 23. Since the non-slip soft rubber pad will deform during the tightening process, when the deformation has a small recovery degree and is irreversible, the non-slip soft rubber pad that first contacts the variable capacitance arc plate 24 will cause the straight seam on the variable capacitance arc plate 24 to deviate during the process of the cylinder 2 856 pushing the tightening plate 857 to tighten the target variable capacitance arc plate 24. If the variable capacitance arc plate 24 is directly sent into the pump housing 21 in this state, it may not be inserted; A power component is provided between the limit plate 852 and the limit ring 853, and the power component includes a motor three fixedly installed on the top of the limit plate 852 and a gear ring 855 fixed on the top of the limit ring 853, and the end of the output shaft of the motor three is fixedly connected with a gear two 854 meshing with the gear ring 855.

[0027] It should be noted that, in the process of loading the variable capacity arc plate 24, when the variable capacity arc plate 24 enters the material taking station of the variable capacity arc plate 24, the cylinder 1 851 will be controlled to push the limit plate 852 to move downward, and drive the top tightening member (composed of the cylinder 2 856 and the top tightening plate 857 installed at the telescopic end of the cylinder 2 856) installed on the outside of the limit ring 853 to extend into the interior of the variable capacity arc plate 24, and then the cylinder 2 856 will be controlled to push the top tightening plate 857 to clamp the variable capacity arc plate 24 to be clamped, and then enter the position of the pump housing 21 with the rotation of the circular plate 82, waiting for unloading; When the clamped variable capacitance arc plate 24 is sent to the corresponding position of the pump housing 21, the image sensor installed on the corresponding straight plate 84 will detect whether the straight seam on the variable capacitance arc plate 24 is aligned with the support plate on the fixed frame 23. If the two are aligned, the variable capacitance arc plate 24 is directly sent into the pump housing 21. If the two are not aligned, the motor three will be started to drive the gear two 854 to rotate, and the rotating gear two 854 will drive the gear ring 855 to rotate, thereby driving the limit ring 853 to rotate, and then cooperate with the information collected by the image sensor to determine whether the straight seam on the variable capacitance arc plate 24 is aligned with the support plate on the fixed frame 23.

[0028] Specifically, Figure 5-Figure 6 and Figure 8As shown, the driving plate loading assembly 86 includes a cylinder three 861 fixedly mounted on the top of the straight plate 84, and the telescopic end of the cylinder three 861 passes through one end of the straight plate 84 and is fixedly connected to a negative pressure suction cup one 862, wherein the driving plate loading assembly 86 also includes a vacuum pump for controlling the negative pressure suction cup one 862 to generate negative pressure.

[0029] It should be noted that in the process of loading the drive disk, when the drive disk enters the material picking station of the drive disk, the cylinder three 861 will be controlled to push the negative pressure suction cup 862 to move downward until it is tightly fitted with the disc 25 on the drive disk, and the vacuum pump will be controlled to evacuate air to allow the negative pressure suction cup 862 to generate a negative pressure, thereby firmly sucking the drive disk, and then it will enter the position of the pump housing 21 as the circular plate 82 rotates, waiting for unloading.

[0030] Specifically, Figure 5-Figure 6 and Figure 12-13 As shown, the end cover loading assembly 87 includes a cylinder 871 fixedly mounted on the top of the straight plate 84, the telescopic end of the cylinder 871 passes through one end of the straight plate 84 and is fixedly connected to a sleeve 872, a T-shaped cylinder 874 is movably inserted inside the sleeve 872, and a negative pressure suction cup 875 is fixedly mounted on the bottom end of the T-shaped cylinder 874, wherein the end cover loading assembly 87 also includes a vacuum pump for controlling the negative pressure suction cup 875 to generate negative pressure, and a sleeve 872 is fixedly connected to the T-shaped cylinder 874 on the outside. Spring three 876, when the end cap 28 to be assembled is sucked up by the negative pressure suction cup two 875, the spring three 876 will be stretched, but the top of the T-shaped cylinder 874 remains plugged into the inside of the sleeve 872, a square groove 877 is provided at the top of the T-shaped cylinder 874, and a square column 878 movably plugged into the square groove 877 is fixedly provided inside the sleeve 872. The arrangement of the square groove 877 and the square column 878 can ensure that the T-shaped cylinder 874 will not rotate relative to the sleeve 872 during the compression of the spring three 876; The end cover feeding assembly 87 also includes a ring plate 873 fixedly mounted on the outer bottom edge of the sleeve 872, and a plurality of electric screwdrivers 879 evenly distributed in a ring shape are fixedly mounted on the ring plate 873, and the output shaft end of each electric screwdriver 879 is fixedly connected to a bolt sleeve 8710.

[0031] It should be noted that, in the process of loading the end cover 28, when the end cover 28 enters the material taking station of the end cover 28, the cylinder 4 871 will be controlled to push the sleeve 872 to move downward, so that the negative pressure suction cup 2 875 installed at the bottom of the sleeve 872 moves downward until it is closely fitted with the end cover 28, and the vacuum pump is controlled to evacuate air, so that the negative pressure suction cup 2 875 generates a negative pressure, thereby firmly sucking the end cover 28, and then entering the position of the pump housing 21 with the rotation of the circular plate 82, waiting for unloading; When the end cover 28 to be sucked up is sent to the corresponding position of the pump housing 21, the cylinder four 871 will push the sucked end cover 28 to move downward. After the end cover 28 is buckled onto the corresponding end of the pump housing 21, the cylinder four 871 will continue to push the sleeve 872 to move downward. At this time, as the sleeve 872 moves downward, the spring three 876 will be gradually compressed. When the bolt sleeve 8710 fixed on the electric screwdriver 879 is sleeved on the locking bolt pre-screwed on the end cover 28, as the sleeve 872 continues to move downward, the electric screwdriver 879 will be powered on and drive the bolt sleeve 8710 to rotate, thereby realizing the use of the locking bolt to fix the end cover 28 to the end of the pump housing 21 in one step.

[0032] Specifically, Figure 5-Figure 6 and Figure 8-Figure 9 As shown, the feeding assembly 83 includes a vertical frame 831 fixed on the top of the base 6, and a sliding platform 832 is movably penetrated on one side of the vertical frame 831. The sliding platform 832 consists of an L-shaped support platform penetrating the vertical frame 831 and a straight bar integrally arranged with the L-shaped support platform. Guide rods 833 movably penetrating the vertical frame 831 are fixed on both ends of the straight bar facing the vertical frame 831. The outer side of each guide rod 833 is sleeved with a spring 834 fixedly connecting the straight bar and the vertical frame 831. A material support 835 for carrying materials is fixed on the top of the L-shaped support platform, wherein, when the spring 834 is in a natural state, the guide rod 833 keeps the state of movably penetrating the corresponding vertical frame 831. At this time, the material support 835 is in the initial feeding position (i.e., the variable capacitance arc plate 24, the drive disk and the end cover 28 to be assembled are placed on the corresponding positions of the material support 835 in cooperation with the robot arm); The feeding assembly 83 also includes three vertical plates 836 fixed at the bottom of the turntable 81 and distributed in an annular manner around the vertical axis. An L-shaped rod 837 is fixedly connected to the middle part of the outer side of each vertical plate 836. A trapezoidal plate 839 is fixedly provided on the inner side of each L-shaped support platform. A push bar 838 is fixedly provided on the outer side of one end of each L-shaped rod 837 away from the corresponding vertical plate 836. The three push bars 838 and the three trapezoidal plates 839 are evenly distributed in the vertical direction.

[0033] It should be noted that, in the process of intermittent automatic feeding of the variable capacitance arc plate 24, the drive disk and the end cover 28, the rotating turntable 81 is used to successively drive the three feeding components 83 to push the variable capacitance arc plate 24, the drive disk and the end cover 28 carried by each of them to the material picking station, and the rotating circular plate 82 will drive the variable capacitance arc plate feeding component 85, the drive disk feeding component 86 and the end cover feeding component 87 to clamp the variable capacitance arc plate 24, the drive disk and the end cover 28 on the corresponding material picking station when entering the material picking station. The specific process (refer to Fig. 9 As shown) are as follows: When the L-shaped rod 837 at the D' position is rotating to the A' position (the angle of a single rotation is 90°), the push bar 838 on the outside of the L-shaped rod 837 will gradually squeeze the trapezoidal plate 839 at the A' position, allowing the sliding platform 832 to move toward the direction of the turntable 81. During this period, the moving L-shaped support platform will pull the straight bar to compress the spring 2 834 at the position. When the turntable 81 rotates 90°, it will stop rotating. At this time, the push bar 838 just pushes the trapezoidal plate 839 at the A' position to the farthest point, and the material support 835 at the A' position just drives the variable-capacitance arc plate 24 at the initial feeding position to move to the corresponding material-retrieving station. At the same time, the variable-capacitance arc plate material assembly 85 will clamp the variable-capacitance arc plate 24 at the material-retrieving station, and the L-shaped rod 837 at the E' position will rotate to the initial D' position; After the variable capacitance arc plate feeding assembly 85 clamps the variable capacitance arc plate 24 at the material taking station, the turntable 81 continues to rotate 90°. During this process, as the L-shaped rod 837 at the initial D' position after one rotation passes over the trapezoidal plate 839 at the A' position, the sliding platform 832 at the A' position will be reset under the restoring force of the corresponding spring 2 834, waiting for the next round of variable capacitance arc plate 24 feeding, and the L-shaped rod 837 at the initial D' position will be reset due to the corresponding L The push bar 838 on the L-shaped rod 837 and the trapezoidal plate 839 at the B' position are staggered, so in this process, the sliding table 832 at the B' position will not move. Similarly, when the L-shaped rod 837 at the E' position moves to the A' position, the sliding table 832 at the A' position will not move. Only when the L-shaped rod 837 at the E' position moves to the B' position, will it push the sliding table 832 at the B' position to move, thereby completing the feeding of the driving disk. Similarly, the L-shaped rod 837 at the F' position will not allow the sliding table 832 at the corresponding position to move when passing through the A' and B' positions, and will only move the sliding table at the C' position when passing through the C' position. Correspondingly, the L-shaped rod 837 at the D' position will not allow the sliding table 832 at the corresponding position to move when passing through the B' and C' positions, and the L-shaped rod 837 at the E' position will not allow the sliding table 832 at the corresponding position to move when passing through the A' and C' positions. In this way, continuous intermittent automatic feeding of the variable-capacitance arc plate 24, the drive disk and the end cover 28 can be achieved, and the structural design is ingenious.

In addition, a plurality of circular rods evenly distributed in an annular shape are further provided at the bottom of the bracket 10, and the bottom end surface of the circular rods is movably fitted with the upper end surface of the bracket 9, so that the bracket 10 is stably supported on the top of the bracket 9, and a clamping and centering mechanism 7 for automatically clamping and centering the pump casing 21 is provided between the bracket 9 and the bracket 10; The clamping and centering mechanism 7 includes a motor 1 fixedly mounted on the top of the base 6 corresponding to the bracket 9 and a boundary strip 71 fixed to the middle of the bottom of the support plate 10. The output shaft of the motor 1 movably passes through one end of the bracket 9 and is fixedly connected to the boundary strip 71. Clamping components are provided on both sides of the boundary strip 71. The clamping assembly includes a gear 72 rotatably mounted on the bottom of the base 6 through an axle rod, two sets of U-shaped frames 75 are fixedly arranged at the bottom of the base 6 and are centrally symmetrically arranged about the gear 72, and the two sets of U-shaped frames 75 are respectively movably penetrated with an L-shaped rack 73 and an L-shaped rack 74 meshing with the gear 72, and a V-shaped block 78 is fixedly arranged at one end of the L-shaped rack 73 away from the boundary bar 71, and a spring 79 is fixedly connected between the end of the L-shaped rack 74 close to the boundary bar 71 and the boundary bar 71, wherein when the spring 79 is in a natural state, the state of the V-shaped block 78 is as follows: Figure 7 The position of the lower end is shown; The clamping assembly also includes two through grooves 76 opened on the base 6, and clamp seats 77 are fitted at the positions of the two through grooves 76 on the top of the base 6, wherein the clamp seat 77 is composed of a vertical block fitted to the upper end surface of the base 6 and a baffle rod fixed on the surface of the vertical block in a V-shaped structure, and connecting blocks slidably connected to the corresponding through grooves 76 are fixed between the L-shaped rack 1 73 and the L-shaped rack 2 74 and the corresponding clamp seat 77.

[0035] It should be noted that the pump housing 21 to be assembled is placed between two clamping seats 77 arranged opposite to each other, and is driven by the motor 1 to move with the support plate 10 to the assembly station (i.e. Figure 5 When the tray 10 is close to the position of one end of the turntable 81 as shown in the figure, when the notch of the turntable 81 is facing the assembly station, the V-shaped block 78 on the clamping assembly of the corresponding assembly station is in the position of extending out of the tray 10 (as shown in the figure). Figure 7The state of the turntable 81 is shown in the lower end position, and then as the turntable 81 rotates, the notch on the turntable 81 will gradually stagger with the V-shaped block 78 of the assembly station. In this process, as the turntable 81 rotates, the turntable 81 will gradually squeeze the V-shaped block 78 of the assembly station, and the pushed V-shaped block 78 will synchronously push the corresponding L-shaped rack 2 74 to move in the direction of the boundary strip 71, and drive the corresponding gear 1 72 to rotate, and the rotating gear 1 72 will drive the corresponding L-shaped rack 1 73 to move away from the boundary strip 71, and stretch the spring 1 79 at the corresponding position. At this time, the two clamping seats 77 will move toward each other, and the pump housing 21 on the assembly station will be automatically clamped and centered; When the V-block 78 of the assembly station is completely offset from the notch on the turntable 81, the two clamping seats 77 that move toward each other complete the centering clamping of the pump casing 21 of the assembly station, and then maintain this state. Under the action of the variable capacity arc plate feeding assembly 85, the drive disc feeding assembly 86 and the end cover feeding assembly 87, the variable capacity arc plate 24, the drive disc and the end cover 28 are assembled into the pump casing 21 in turn, completing the automatic assembly action of the pump body 2.
